The snow is now 52 inches deep. If this was a 77%
decrease, what was the initial depth

Answer: The answer would be B -2

Step-by-step explanation:It is B because if you put -1 in the equation then that would mean -3 * -2 would be 6 and then you would add 2 which would mean that 6 + 2 would give you the answer of 8 so therefore your answer is B. -2

that how i solved it

Answer:

Step-by-step explanation:

The odds for 4 heads = (1/2)^4 = 1/16..

So the odds against is 1 - 1/16 = 15/16.

The odd against the coin showing heads all four times if, A coin is tossed four times is 15 / 16.

The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.

Given:

A coin is tossed four times,

Total outcomes = (head or tail) × 4 =  2 × 4 = 16

Total favorable outcomes = head = 1,

Calculate the probability of the coin showing a head all four times as shown below,

Probability = Total favorable outcomes / Total outcomes

Probability = 1 / 16

Calculate the odd against the coin showing heads all four times as shown below,

The odd against the coin showing heads all four times = 1 - The probability of the coin showing a head all four times

The odd against the coin showing heads all four times = 1 - 1 / 16

The odd against the coin showing heads all four times = 15 / 16.

Answer: The answer is f= –31 1/3.

Step-by-step explanation: To solve for f, you’ll need to simplify the both sides of the equation, and then isolating the variable. Use online advanced calculators to calculate the equation to view all the steps.

Answer: x= -56/9

Step-by-step explanation:

34+12x=3x-22

Subtract 12x from both sides

34=-9x-22

Add 22 to both sides

56=-9x

Divide -9 by both sides to get x alone

56/-9=x

So

x=-56/9

Step-by-step explanation:

So, first we must find the price per ticket so we do

13.80/5 = 2.76

So the $2.76 per ticket

So now all we do to find the price of three tickets we times the price per ticket by 3

2.76 x 3 = $8.28

Answer:

C.

Step-by-step explanation:

It's hard to explain, but trust me :)

5 is subtracted by 4 times a number. 4 times a number is 4x, because x is the unknown number. That would be 4x-5

Then, it says that 4x-5 is greater than 8 times a number. Again, 8 times a number is 8x because x is the unknown number.

And remember, > is greater than, and < is less than.

Hopefully you understand this problem for another time.

Answer:

The value  is  [tex]n = 384 [/tex]

The correct option is a

Step-by-step explanation:

From the question we are told that

   The margin of error is  E =  0.05

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of   is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally since the sample proportion is not given we will assume it to be

      [tex]\^ p = 0.5[/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>   [tex]n = [\frac{ 1.96 }{0.05} ]^2 *0.5 (1 - 0.5) [/tex]

=>   [tex]n = 384 [/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

Generally if the level of confidence increases,  the critical value of  [tex]\frac{\alpha }{2}[/tex]  increase and from the equation for margin of error we see the the critical  value varies directly with the margin of error , hence the margin of error  will increase also  

So  If the confidence level is increased, then the sample size would need to increase because a higher level of confidence increases the margin of error.

Answer:

  $7,358

Step-by-step explanation:

Assuming the interest is compounded annually, the amortization formula is useful here.

  A = Pr/(1 -(1+r)^-t)

A is the annual scholarship, P is the principal invested at rate r for t years.

  A = $100,000(0.04)/(1 -1.04^-20) = $7,358.18

The university could give $7,358 in scholarships each year.
